DAMPER WEIGHTS

Damper weights are used on the left driveshaft assemblies of all front wheel drive vehicles (Fig. 1). These weights are attached to the interconnecting shaft and are available as a separate service part. They should be removed from the driveshaft assembly during driveshaft positioning specification procedures. When the weights are attached between the locating shoulders, tighten the fasteners to the following specifications:

²S.S.G. Ð 28 NIm (21 ft. lbs.)

²G.K.N. Ð 30 NIm (23 ft. lbs.)

SUSPENSION/DRIVESHAFTS 2 - 49

(1)The vehicle must be completely assembled. Front wheels must be properly aligned and in the straight ahead position. The vehicle must be in a position so that the full weight of the body is distributed to all four tires. A platform hoist, or front end alignment rack, is recommended.

(2)Using a tape measure or other suitable measuring device. Measure the direct distance from the inner edge of the outboard boot to the inner edge of the inboard boot on both driveshafts. This measurement must be taken at the bottom (six o'clock position) of the driveshafts (Fig. 1).

DRIVESHAFT POSITIONING SPECIFICATIONS

Front wheel drive vehicles have engine mounts with slotted holes allowing for side to side positioning of the engine. If the vertical bolts on the right or left upper engine mount have been loosened (e.g., engine removal and installation) for any reason, or if the vehicle has experienced front structural damage, driveshaft lengths must be checked and corrected, if required. A shorter than required driveshaft length can result in objectionable noise. A longer than required driveshaft length may result in potential damage.

Use of the following procedure will ensure satisfactory driveshaft engagement under all normal vehicle operating conditions.

Fig. 1 Driveshaft Positioning

Note that the required dimension varies with carline, engine, transaxle, and driveshaft manufacturer (Fig. 2).

(3)If the lengths of both shafts are within the range specified, no further action is required.

If either the left or right shaft length is not within the specified range. Refer to Engine, Group 09, Engine Removal and Installation to properly position the engine according to the driveshaft lengths specified.

(4)If proper driveshaft lengths cannot be achieved within the travel limits available in the slotted engine mounts. Check for any condition that could effect the side to side position of the measurement locations (e.g., engine support brackets, siderail alignment, etc.).

(5)After ensuring proper driveshaft lengths the transmission shift linkage must be adjusted to ensure proper operation. Refer to Transaxle, Group 21.
